HIGHLIGHTS
- who: Naoki Matsumoto and Yumiko OHNO from the (UNIVERSITY) have published the research: Facial Achromatic Number of Triangulations with Given Guarding Number, in the Journal: (JOURNAL)
- what: The authors investigate the relation between the facial 3-achromatic and guarding of triangulations on a surface where a guarding of a graph G embedded on a surface denoted by guard(G) is the smallest size of its guarding set which is a generalized concept of guards in the art gallery problem. The authors show that for any graph G embedded on a surface ψ∆(G ) (G) ≤ guard(G . . .
